Canned Corn Calorie Breakdown
For most common varieties, a standard 100-gram serving of canned sweet corn that has been drained of its liquid contains approximately 71 calories. This calorie count is based on the whole kernels themselves, without considering the extra water or brine. The majority of these calories come from carbohydrates, specifically the natural sugars and starches present in the corn kernels. It is important to note that the exact caloric value can differ slightly depending on the brand and whether any extra ingredients, like sugar or salt, were added during the canning process.
Nutritional Composition of 100g Canned Corn
Beyond just calories, 100 grams of drained canned corn provides a range of other essential nutrients.
- Carbohydrates: The largest contributor to the calorie count is carbohydrates, with about 15 grams per 100-gram serving. These are a source of sustained energy for the body.
- Protein: Canned corn contains a small but valuable amount of protein, typically around 2 grams per 100g.
- Fat: It is naturally low in fat, with about 1 gram per serving. A very minimal portion of this is saturated fat, making it a heart-healthy choice.
- Fiber: This food item is a good source of dietary fiber, offering about 2 grams per 100g serving. Fiber is crucial for digestive health and helps promote feelings of fullness.
- Vitamins: It provides a good dose of B vitamins, especially folate (Vitamin B9), which is important for cell function. It also contains some Vitamin C.
- Minerals: Key minerals include potassium, magnesium, and phosphorus, all of which play vital roles in overall health.
Canned vs. Fresh vs. Frozen Corn
While canned corn is convenient, many wonder how its nutritional profile compares to fresh or frozen versions. The difference in calorie count is often minimal, but preparation and processing can alter other nutritional aspects, particularly sodium content. Fresh, raw sweet corn typically contains slightly more water and a little less sugar by weight, but the overall macronutrient breakdown per 100 grams is very similar to its canned counterpart after accounting for liquid. Frozen corn is flash-frozen at its peak ripeness, effectively locking in nutrients. A key difference to consider is that canned corn often has added sodium, whereas frozen or fresh corn can be prepared with minimal or no salt, making them a better choice for those monitoring sodium intake.
| Nutrient (per 100g) | Canned Corn (Drained, Sweet) | Fresh Corn (Boiled, Sweet) |
|---|---|---|
| Calories | 71 kcal | 96 kcal |
| Carbohydrates | 15 g | 21 g |
| Protein | 2 g | 3.4 g |
| Fat | 1 g | 1.5 g |
| Fiber | 2 g | 2.4 g |
| Sodium | 185 mg | 1 mg |
Note: Nutritional values can vary slightly between sources and specific product types. The lower calorie and carbohydrate count for canned corn (drained) is primarily due to the canning process removing some of the water-soluble compounds and the high-calorie liquid being discarded. However, fresh corn data often includes the inherent moisture from boiling.
